[Resolved] Change font and font size

putting it mildly I’m not a really good coder – each time I’ve to change code it’s more or less a nightmare for me. Bit this time it’s no use, I’ve to face the problem …

I’m running a sports clubs homepage, using wordpress and raindrops. Now, the headlines of the entries are printed quite big and in some serif-style font (I guess it’s something like Times New Roman). This is something I’d like to change. I already had a look into style.css, but I can’t get a clue where to do the changes.
